Local residents in Riverside County, California - an enclave east of Los Angeles where the trendy music festival is slated for next month - are circulating a petition to cancel the chic shindig, citing fears that it could bring the epidemic with it.

"The low desert's population is densely seniors, which are at significantly higher risk of developing complications from COVID-19," Annette Meza of nearby Fontana commented on the petition on Change.org, which more than doubled to 12,000 signatures over the weekend.

"This is a HUUGE gathering by people who can't even keep herpes to themselves!!!" wrote Lyssa Perez of neighbouring Palm Desert.

Scoop: A source familiar with the arrangements tells me that the Coachella festival will be postponed due to Coronavirus concerns and moved to the weekends of October 9 and 16.

Meanwhile, a Change.org petition not to cancel Coachella - which is scheduled for the weekends of April 10 and April 17 - has garnered some 1300 signatures.

"The valley needs the revenue so don't panic," wrote Evelyn Eccard of Redondo Beach, California.

"I'm at the age where I can get the coronas and sleep it off the next week," added Avery Pyatt of Pittsburgh.

According to the Coachella Valley Economic Partnership, Coachella and its subsidiary Stagecoach festival in 2017 brought in $US400 million (SA607.7 million) to Coachella Valley and $US700 million ($A1.06 billion) to the metro area.

Over the weekend, however, Riverside County got its first coronavirus case, as a patient was confirmed at Eisenhower Medical Center in Rancho Mirage, about 40km from the festival site.

The event - whose line-up this year includes Frank Ocean, Lana Del Ray, Travis Scott and Rage Against the Machine - was already on shaky ground after news hit on Friday that South by Southwest, the Austin, Texas-based music and tech festival, was cancelled.

Music bigwigs are wringing their hands because Coachella kicks off a slew of music festivals through the summer, including New Orleans Jazz Fest, CMA Music Festival, Bonnaroo Music Festival, Lollapalooza and Burning Man.

Nevertheless, if there is a cancellation, Kaiser said officials will give "as much lead time as possible to enable these vital components of our economy to continue to take place in later years, while keeping their attendees and all residents of Riverside County safe."

Reps for Coachella and GoldenVoice, the AEG subsidiary that produces the event, did not return requests seeking comment.
